“The Line” is Saudi Arabia’s bold vision for the future of civilization: an ultra-modern city designed to house 1 million people and be entirely pollution-free. ↠Subscribe: https://www.youtube.com/c/TerraMaterOfficial?sub_confirmation=1

But there’s one problem – it’s in the middle of the desert. And cities require a lot of water.

Enter the Solar Dome, a new desalination system built on existing technology. It’s supposed to be a low-cost, efficient, and carbon-neutral way of turning saltwater into fresh water. With water scarcity already threatening the Middle East, Saudi Arabia is the world leader in desalination, but the process does pose problems. We take a closer look at the environmental costs of desalination, and how new innovation like the Solar Dome is trying to tackle these issues.

    Correct me if im wrong but arnt the minerals in the brine useful? The salt and silica are both high value byproducts.

    So a giant solar still basically.

    This video is outdated. Israel is indeed already refilling the Sea of Galilee with desalinated water. They’re sharing tons of Galilee’s freshwater with Jordan, so where’s the crisis?

    use black trash bags instead. they work like your normal cactus plants.

    Can't we make a fuel from the salt to run the desalination process?

    In Vienna we’re extremely lucky ! We got our water from the mountains ( the Alps ) which is one of the best water in all Europe, efficient and cheap

    Great video!

    Why don't they just paint the domes black instead of using the mirrors. It may take a little longer, but there will be a huge amount of heat inside there to cause evaporation, instead of using costly mirrors that are also costly and labor intensive to maintain.

    One solution may be to allow the evaporation vessel (6:27) to build up salt until it has a reasonable amount and every few months, years, (whatever) the salt is excavated and sold as a commercially viable by product. Even if little profit was made it is far better than spending vast amounts on getting rid of it.

    They stole my idea. i been saying to use solar domes for desalination for at least 10 years now. Its good either finally someone heard me or another great mind like mine.

    Stop pretending to be so helpless about what to do with the salt after desalinization. Sell it! Stop wringing your hands saying, "Whatever shall we do ….. My goodness!"

    Instead of exploiting desalination forever; why not to use it to create artificial rivers and ponds capable to create new aquifers in the long term?

    how about creating frashwater,electricity and domestic salt with solar energy in a single plant
